Term
The spefic heat of copper is 0.385J/g C. Wgucg equation would you use tio calculate the amount of heat needed to raise the temperature of 0.75 g of copper from 7degreesC to 29degrees C>
Q=0.385J/g c X 29C -7C)
Q=0.75g x0.985J/gC x29C
Q=0.75g x0.385 J/gC x22C
Q=0.75x0.85J/g C x & C
Definition
Q +0375g x 0.85J/g degrees c x22 c
